VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 778,631, dated December2'7, 1.904. Application filed Julie 22, 1904. Serial N- 213,698.

To @ZZ whom t 717/603/ concern:

Be it known that I, CALVIN A. BUFFINGTON, a citizen of the UnitedStates, residing at Berkshire, in the county of Tioga and State of NewYork, have invented new and useful Improvements in Vehicle-Brakes, ofwhich the following is a specification.

My invention relates to new and useful irnprovements in ifchicle-brakes;and its object is to provide a simple and inexpensive device of thischaracter which can be readily applied to various forms of carriages andwagons and which is practically unnoticeable except when applied.

A further object is to provide a brake which is adapted to contact withthe ground at a point removed from the rear wheels of the vehicle andraise one or both of said wheels from the ground.

Vith the above and other objects in view the invention consists ofbrackets adapted to be secured to the rear axle of a vehicle andprovided with hangers which are pivoted thereto and are pivotallyconnected to a beam having a resilient brake-shoe extending therefrom.The other end of the beam is pivoted to a crank extendingr from a shaftwhich is fulcrunied upon the wagon-body and is adapted to be rotated bymeans of a foot-lever provided for that purpose.

The invention also consists in the further novel construction andcombination of parts hereinafter more fully described and claimed,

and illustrated in the accompanying drawings, I

showing the preferred form of my invention, and in which- Figure 1 is aside elevation of a vehicle having my improved brake connected thereto,the brake beingshown out of applied position and a portion of thevehicle-body being removed to show the foot-lever and the partsconnected thereto. Fig. 2 is a view similar to Fig. 1, but showing thebrake applied. Fig. 3 is a rear elevation of the vehicle with the partsin the positions shown in Fig. 2. Fig. 4 is a detail view of the brakebeam and shoe. Fig. 5 is a detail view of the foot-lever, and Fig. 6

y is a view similar to Fig. 3 and showing a modified form of brake.

Referring' to the figures by numerals of reference, 1 is a vehicle-bodysupported upon axles 2 and 3, on which are arranged wheels 4. Secured tothe rear axle 2, at one side of th ecenter thereof, areinternally-screw-threaded blocks 5, in which is mounted a screwthreadedrod 6, having' an integral arm 7 at one end, said arm being braced by arod 8, which is secured to one end of the rod 6 and adjacent the freeend of arm 7. This arm 7 is pivoted to a beam 9, which is provided atits rear end and adjacent its point of connection with arm 7 with a shoe10, preferably formed of heavy sheet metal of a resilient nature.Parallel ears 11 extend from the other end of beam 9 and have apertures12 for the reception of a pin 18. This pin engages one end of a crank14, which depends from a shaft 15, revolubly mounted in bearings 16,located upon the bottom of the vehicle-body 1. Another crank, 17, islocated at the other end of shaft 15 and is connected by a link 18 witha foot-lever 19, pivoted at one end to a plate 20.

adapted to be secured to the bottom of the vehicle-body. The link 18 ispreferably connected to lever 19 ata point between the ends thereof.

It will be seen that when the lever 19 is pressed downward upon thebottom of the vehicle-body 1 the cranks 17 and 14 are swung so as todraw arm 7 forward. Beam 9 is therefore raised into the position shownin Fig. 1, where it is close to the .vehicle-bod y and practicallyunnoticeable. Then it is desired to apply the brake, foot-lever 19 ispressed forward and causes crank 14 to swing backward. A similarmovement is imparted to arm 7; but as said arm is longer and lower thanthe crank 14 it is obvious that the shoe 10 atthe rear end of beam 9will swing downward into contact with the ground, and the forwardmovement of the wheels 4, in addition to slight pressure which may beexerted upon the lever 19, will cause the shoe 10 to-bear tightly on theground and raise the rear wheels. As the shoe 10 is made of resilientmetal, it will be understood that jarring `of the vehicle during theapplication of the brake is prevented. Moreover, by

screw-threading rod 6 said rod can be rotated without becomingdisplaced, and it is unnecessary to use nuts or other securing devicesfor IOO locking the rod in position. However, instead of using thescrew-threaded rod I may, if desired, employ the construction shown inFig. 6. By referring to said figure it will be seen that brackets 21 arefastened to the rear axle of the vehicle, and pivoted to these bracketsare hangers 22, which are pivoted to ears 23, located at opposite sidesof the brake-beam 2A.

I/Vhile I have shown the brake-beam located at the center of thevehicle, it will be understood that, if desired, it may be arranged atone side of the center, so as to raise only one wheel when applied. Thebrake is very simple and compact in construction and can be readilyattached to almost any form of vehicle. INhen it is not in use it isunnoticeable, and by employing it the wheels of the vehicle are notsubjected to the wear and tear which is ordinarily produced by the useof brake-shoes which are adapted to contact with the tires of thewheels.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing' from the spirit orsacrificing any of the advantages thereof, and I therefore re serve theright to make such changes as fairly fall within the scope of myinvention.

Having thus described the invention, what is claimed as new is l. rIhecombination with a vehicle-body, axles, and wheels for supporting thesame; of a brake-beam, a resilient shoe at one end thereof, supportingdevices pivoted to the vehiclebody and one of the axles, respectively,and to opposite portions of the beam, an operating-lever within thebody, and a link connecting the lever with one of the supportingdevices.

2. The combination with a vehicle-body, axles therefor, and wheels forsupporting the same; of internally-screw-threaded blocks connected toone of the axles, a screw-threaded rod extending therethrough, an armupon the rod, a crank-shaft upon the vehicle-body, a brake-beam pivotedto the crank-shaft and arm, a spring-shoe extending from one end of l ll l the beam, and means for operating the crankshaft.

3. The combination with a vehicle-body, axles therefor, and wheels forsupporting the axles; of internally screw threaded blocks connected toone of the axles, a screw-threaded rod extending therefrom, an arm atone end of the rod, a brake-beam pivoted to said arm and normally inposition between the axles, a crank-shaft journaled upon the body andconnected to the beam, a lever, and a link connecting' the lever and thecrank-shaft.

4. The combination with a vehicle-body, axles therefor, and wheels forsupporting the same; of internally screw -threaded blocks secured to oneof the axles, a screw-threaded rod extending therefrom, an arm upon therod, a brace therefor, a brake-beam pivoted to the arm and normally inposition between the axles, a shaft upon the vehicle-body,oppositely-extending cranks thereon, one of said cranks being' pivotedto the beam, an operat ing-lever, a link connecting the other crank withsaid lever, and a spring brake-shoe cxtending from one end of the beam.

5. A brake for vehicles comprising internally-screw-threaded blocks, ascrew-threaded rod extending therefrom, an arm at one'end of the rod, ashaft, cranks thereon, a brakebeam pivoted to the arm and one of thecranks, a brake-shoe extending from one end of the beam, anoperating-lever, and a link connecting one of the cranks with saidlever.

6. The combination with a vehicle-body, axles, and wheels for supportingthe same; of threaded blocks connected to one of the axles, a rodadjustably engaging the blocks, an arm extending from the rod, abrake-beam pivoted to the arm, a supporting and operating deviceconnecting the beam and vehicle-body, and a shoe at one end of thebrake-beam.

In testimony whereof I afiix my signature in presence of two witnesses.

CALVIN A. BUFFINGTON.
